EMC Sealing System and Method for an Electrical Enclosure

1. An apparatus for providing an electromagnetic conduction seal in a device disposed within an electrical enclosure comprising: a metal EMC gasket defined by a first end and an opposite second end, said first end is operably secured to the device, at least said second end is allowed to float while remaining in electrical contact with the device; and a lock strip fixed to the device, said lock strip configured to provide limits of deflection of an intermediate portion of said gasket intermediate said first and second ends and captivate at least one floating end of the gasket; wherein said intermediate portion provides an electromagnetic conduction seal between the device and with at least one of another device and the electrical enclosure.

2. The apparatus of claim 1 , wherein when said lock strip is configured to captivate just said second end, said first end is fixed to the device.

3. The apparatus of claim 1 , wherein said lock strip configured to provide limits of deflection of said intermediate portion of said gasket intermediate said first and second ends includes a member extending toward said intermediate portion a distance therefrom representing said limit of deflection.

4. The apparatus of claim 1 , wherein said lock strip is defined by two opposite ends configured to each captivate but allow float of each of said first and second ends of said gasket.

5. The apparatus of claim 1 , wherein said lock strip comprises: a base fixed to the device; a member extending from said base toward said intermediate portion of said gasket; and at least one arm extending from one of said base and said member, said at least arm configured to captivate one of said first and seconds ends between said arm and the device and allow float of the same.

6. The apparatus of claim 5 , wherein said at least arm is configured having an offset arm defined by an end portion substantially parallel to said base.

7. The apparatus of claim 1 , wherein said intermediate portion of said gasket is a bight portion configured to flex allowing the device extraction and insertion while still making a suitable ground contact.

8. The apparatus of claim 7 , wherein said bight portion is segmented transversely along a length defining said gasket to facilitate compression thereof.

9. An apparatus for providing an electromagnetic conduction seal in a device disposed within an electrical enclosure, said apparatus comprising: a housing, having a housing base, a housing cover and a housing wall, wherein said housing base and said housing wall are disposed relative to each other so as to define a housing cavity for containing an electrical device; a housing bezel, said housing bezel is disposed relative to said housing so as to be associated with a cable opening and in electrical communication with the electrical device; a metal EMC gasket defined by a first end and an opposite second end, said first end is operably secured to the device, at least said second end is allowed to float while remaining in electrical contact with the housing bezel; and a lock strip fixed to the housing bezel, said lock strip configured to provide limits of deflection of an intermediate portion of said gasket intermediate said first and second ends and captivate at least one floating end of the gasket; wherein said intermediate portion provides an electromagnetic conduction seal between the device and with at least one of another device and the electrical enclosure providing electromagnetic shielding for the electrical device disposed within said housing.

10. The apparatus of claim 9 , wherein when said lock strip is configured to captivate just said second end, said first end is fixed to the housing bezel.

11. The apparatus of claim 9 , wherein said lock strip configured to provide limits of deflection of said intermediate portion of said gasket intermediate said first and second ends includes a member extending toward said intermediate portion a distance therefrom representing said limit of deflection.

12. The apparatus of claim 9 , wherein said lock strip is defined by two opposite ends configured to each captivate but allow float of each of said first and second ends of said gasket.

13. The apparatus of claim 9 , wherein said lock strip comprises: a base fixed to the housing bezel; a member extending from said base toward said intermediate portion of said gasket; and at least one arm extending from one of said base and said member, said at least arm configured to captivate one of said first and seconds ends between said arm and the device and allow float of the same.

14. The apparatus of claim 13 , wherein said at least arm is configured having an offset arm defined by an end portion substantially parallel to said base.

15. The apparatus of claim 9 , wherein said intermediate portion of said gasket is a bight portion configured to flex allowing housing extraction and insertion while still making a suitable ground contact.

16. The apparatus of claim 15 wherein said bight portion is segmented transversely along a length defining said gasket to facilitate compression thereof.

17. A method for providing an electromagnetic conduction seal in a device disposed within an electrical enclosure, the method comprising: configuring a metal EMC gasket defined by a first end and an opposite second end, said first end is operably secured to the device, at least said second end is allowed to float while remaining in electrical contact with the device; fixing a lock strip to the device; configuring said lock strip to provide limits of deflection of an intermediate portion of said gasket intermediate said first and second ends; and captivating at least one floating end of said gasket, wherein said intermediate portion provides an electromagnetic conduction seal between the device and with at least one of another device and the electrical enclosure.

18. The method of claim 17 , wherein said configuring said lock strip to provide limits of deflection of said intermediate portion of said gasket intermediate said first and second ends includes a member extending toward said intermediate portion a distance therefrom representing said limit of deflection.

19. The method of claim 17 , wherein said intermediate portion of said gasket is a bight portion configured to flex allowing device extraction and insertion while still making a suitable ground contact.

20. The method of claim 19 , wherein said bight portion is segmented transversely along a length defining said gasket to facilitate compression thereof.
